When you install the refFunctions plugin, you can use the Field
Calculator to create an aggregate field with a formula like this:
intersecting_geom_sum('table2', 'column_value2')
This will search all points in table2 intersecting with features in
table1, add the values from column_value2 and write the sum to table1.
